Linux CentOS6.5 yum 安装

一：将现有的yum源卸载

# rpm -qa yum

# rpm -qa | grep yum | xargs rpm -e --nodeps #这一步一定要执行，而且要将所有的组件卸载掉，如果卸载不干净，后面安装会有问题

# rpm -qa yum

 

二、从centos官网上下载和yum有关的rpm包

contos7:

 # wget http://mirror.centos.org/centos/7/os/x86_64/Packages/yum-3.4.3-150.el7.centos.noarch.rpm
 # wget http://mirror.centos.org/centos/7/os/x86_64/Packages/yum-metadata-parser-1.1.4-10.el7.x86_64.rpm
 # wget http://mirror.centos.org/centos/7/os/x86_64/Packages/yum-plugin-fastestmirror-1.1.31-40.el7.noarch.rpm
  

contos6:

http://mirror.centos.org/centos/6/os/x86_64/Packages/yum-3.2.29-81.el6.centos.noarch.rpm
http://mirror.centos.org/centos/6/os/x86_64/Packages/yum-metadata-parser-1.1.2-16.el6.x86_64.rpm
http://mirror.centos.org/centos/6/os/x86_64/Packages/yum-plugin-fastestmirror-1.1.30-40.el6.noarch.rpm
 

我的是6.5，但这个rpm包软件里面有，分别是：

yum-3.2.29-40.el6.centos.noarch.rpm

yum-metadata-parser-1.1.2-16.el6.x86_64.rpm

yum-plugin-fastestmirror-1.1.30-14.el6.noarch.rpm

 

三：安装

 

#  rpm -ivh yum-* #安装

# rpm -qa yum #查看是否已经安装上

CentOS6 yum时File contains no section headers.解决办法：

1: 

 #  rm -f /etc/yum.repos.d/*  

contos7:

# wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-7.repo 

contos6:

#wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-6.repo 

# yum clean all
